Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Out-of-bounds read vulnerability exists in CX-Programmer included in CX-One CXONE-AL[][]D-V4 Ver. 9.81 or lower. Opening a specially crafted project file may lead to information disclosure and/or the product being crashed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

An out-of-bounds read vulnerability exists in CX-Programmer (part of CX-One suite) when parsing specially crafted project files. The vulnerability allows reading beyond allocated memory boundaries, potentially exposing sensitive memory contents and causing application crashes.

MitigationApply vendor patch (Ver. 9.82 or higher) when available. Until then, avoid opening project files from untrusted sources and implement file import restrictions in the industrial environment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm CX-Programmer installation
    Check for CX-Programmer installation by searching program directories or using system inventory tools. Common paths: C:\Program Files\OMRON\CX-Programmer or C:\Program Files (x86)\OMRON\CX-Programmer
    Affected if CX-Programmer from the CX-One suite is installed on the system
  2. Identify installed CX-Programmer version
    Locate the CX-Programmer executable (usually CX-Programmer.exe) and check its version property, or check in Windows Programs and Features. The version is typically displayed as a product version in the format X.XX
    Affected if The installed version is lower than 9.82 (versions below 9.82 are vulnerable)
  3. Verify project file handling capability
    Check if CX-Programmer is configured to allow importing or opening project files (.cxp, .cxt, or other CX-Programmer file extensions) from external or network locations
    Affected if Users can import or open project files from untrusted or external sources, enabling the attack vector
  4. Check for recent CX-One suite updates
    Use Windows Update or check OMRON's official support site for CX-One suite patches to see if version 9.82 or higher has been applied
    Affected if The installed CX-Programmer version remains below 9.82 and no vendor patch has been applied

A system is affected if CX-Programmer from the CX-One suite is installed with a version lower than 9.82 and users can open or import project files from potentially untrusted sources.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patch (Ver. 9.82 or higher) when available. Until then, avoid opening project files from untrusted sources and implement file import restrictions in the industrial environment.

Recommended fix Moderate confidence

CX-One CXONE-AL[][]D-V4 Ver. 9.82 or later (any version above 9.81)

  1. Download the latest version of CX-One (CXONE-AL[][]D-V4) from the official Omron website or through your existing license/Support Download portal
  2. Uninstall the current version of CX-Programmer/CX-One before installing the new version to ensure a clean installation
  3. Install the updated CX-One package which includes the patched CX-Programmer component
  4. Verify the installation by checking the program version information in CX-Programmer (Help > About CX-Programmer)
  5. Do not open untrusted or unsolicited project files in CX-Programmer as a general security practice
